Is there any way to determine whether the wing tanks in an already skinned wing were built using vinylester instead of epoxy?
A KR builder has a set of wings with Diehl skins already built. Older wings apparently off of what was a flying airplane, but NO information about what was used to build the fiberglass tanks? The wings are marked: 100LL ONLY. So, maybe they weren't built using vinylester?? I don't want to chance buying the wings without knowing what I'm getting!! Thanks, Ron
